The only thing we need fear - is fear itself.

In just one morning the neatly organised world of Cory Wilson falls apart. The sun has been extinguished, plunging the Earth into total darkness. Terror reigns. Unable to think of anything else to do, Wilson places his faith in Billionaire Barry Castle’s radio announcement of a Doomsday Dome being constructed in rural Montana – a sanctuary where all who can reach it will be safe from the lethal cold to come. There is just one catch – the only way to find it is by solving Castle’s riddle. With the uninvited help of former Advertising Executive Jenny Edwards, Wilson sets out on a dangerous journey to solve the riddle and survive the apocalypse.
